Abstract
We present a novel surface-emitting GaAs/AlGaAs laser diode beam steering device, which is based on a surface mode emission process. The coupling of the laser mode to a surface mode results in surface emission with a beam divergence of 0.4°, which is steerable at a rate of dα/dλ=-0.245°/nm by a tuning of the laser emission wavelength. The continuous control of the surface mode dispersion by external parameters allows a definite adjustment of the emission angle. In addition, the feedback of the surface mode to the laser mode provides a kind of single mode operation.
